Nested XML - CData inconsistencies
----------------------------------
Key: XMLBEANS-241
URL: http://issues.apache.org/jira/browse/XMLBEANS-241
Project: XMLBeans
Type: Bug
Components: XmlObject
Environment: XP Professional
Reporter: Keith Daurs
Priority: Critical
Trying to insert XML data into an existing XML document. Success of this
operation appears to be dependant on the size of data held in the nested XML
child elements. Operation works fine up to a certain size with nested XML
correctly wrapped within CDATA. However, if child elements are over a certain
size then nested XML is not recognised as CDATA and the <> chars are escaped,
causing parsing problems further down the line.
For an example I have used the EasyPO xsd as provided on the XMLBeans website,
and adding the folowing data as my nested XML:
SUCCESSFUL RUN
<nestedXML>
<testData>
<textDataOne>hello world hello world hello world hello world hello
world hello world hello world hello world hello world hello world hello world
hello world hello world hello world hello world hello world hello world hello
world hello world hello world hello world hello world hello world hello world
hello world hello world hello world </textDataOne>
<sizeTextDataOne>324 bytes</sizeTextDataOne>
<textDataTwo>hello</textDataTwo>
<sizeTextDataTwo>5 bytes</sizeTextDataTwo>
</testData>
</nestedXML>
Output as follows:

Example code used:

import org.apache.xmlbeans.XmlObject;
import org.openuri.easypo.LineItem;
import org.openuri.easypo.PurchaseOrderDocument;

public class XMLBeanTester

public static void main(String[] args)
{
new XMLBeanTester().testXMLBeans();
}
public void testXMLBeans()
{
File xmlFile = new File("myPO.xml");
String test_XML_data = "nested_xml.xml";
try
{
PurchaseOrderDocument PODoc =
PurchaseOrderDocument.Factory.parse(xmlFile);
XmlObject xml = XmlObject.Factory.parse(new
File(test_XML_data));
LineItem item =
PODoc.getPurchaseOrder().addNewLineItem();
item.setDescription(xml.xmlText());
PODoc.save(new File("myNewPO.xml"));
}
catch (XmlException e)
{
System.out.println("XML Problem:- ");
e.printStackTrace();
}
catch (IOException e)
{
System.out.println("IO Problem:- ");
e.printStackTrace();
}
}
}
Is this a known bug or I am I missing something fundamental (quite possible!)?
Any input will be appreciated as this is now having a serious impact on our
project.
